To all whom it may concern:

Be it known that I, GYURO E. B. JAKO- rn'rs, a subject of the Emperor ofAustria, residing at Chicago, inthe county of Cook a-nd ,.Sta t-eof'Illinois, have invented certain new and useful ImprovementsinPermuta- (ion-Padlocks, of which'the following is specification. I pThis invention relates to new and useful improvements in permutationpad-locks.

Theprimary-obj ect of the invention is the provisionof a permutationpad-lock possess- ,ing great strength and adapted for operation in.connection with permutation members, the structure being easy andinexpenslveto manufacture.

The further .ob ec t of the device is to pro-.'

- vide a .permutation pad-lock having a seper-able shackle the samebeing maintained in. its locked position when desired by means oflaplurality of permutation members rele a sable by a personlwho isfamiliar; with the combination thereof.

A still further, object of the invention the provision of a permutationpad-lock whichlcannot be picked nor released by an unauthorized person,the same requiring a knowledge of the combination of permutation membersW1th which the same is provided in order to unlock the d'eyice.

Fig. 3 is a top plan view of the device partly broken away.

Fig. 4. is a detail perspective View of the main shaft member of thelock and a portion of the shackle support.

Fig. 5 is a similar perspective View of the bolt member of the deviceand Figs. 6 and .7 are end views of the two different forms.ofpermutation members employed with the device.

Referring more in detailto the drawing ashaft 10 is provided centrallyprojectingv from a circular disk or head 11 formedat one, end of thedevice upon one arm 12,;of a

shackle section 13. J A similar head 14;. -nor 'mally maintainedopposite the head 11 is provided with a bolt 15 rectangular crossSpecification of LettersPatent-t ters such as the letters 27' hereinshown,

section and adapted for slidable reception with n a longitudinalside-slot 16 of the shaft 10. I

The head 1 1 is carriedby an arm 17 hav- 6'0 inga' shackle section 1.8at its opposite end,

b th of the shackle sections "13 an'dlS being "substantially U-sha-pcdand forming the re calving opening 19 of the lock when the bolt 15 isoperatively positioned within the slot '16 and with the free end 20 ofth bolt in. substantial engagement centrally with the head 11.

The shackle section 13 has its opposite sides .21 provided with 'sockets22-adapted for the reception of dowel pins 23- carried by the oppositesides 24 of the shackle section 18. "A plurality of permutation members25 and a slightly different'siugle peirnnita tion'me'mber '26 arejournal'ed upon 'theshaft 10- and are provided with desirable charawhich by means of the-arrangement hereinafter set, forth control thelloc'kingand unlocking of the'device during the action .of apredeterminedturning of the permutation ,7 members.

Radially-projecting lugs-:28 are suitably positioned opposite each otherv, upon the shaft 10' while similar-lugs 29 are provided from the shaft10 when the bolt is seated be noted the lugs 2Sand 29 are arranged", ini Each of the permutation members 25-and 26 is of cylind'ricalconstruction, being 1a a maybe journaleduuponl the; shaft the-bolt 15 isseated :withinqi-th slot.

Opposite radial slots 31 and 32 are provided" in the opposite sides ofthe members 2-5 adapted for permitting the members 25 to be moved overthe lugs 28, receiving the said lugs 28 Within the members 25. The slots32 of the members 25 and 26 are of greater width than the slots 31whereby the members 25 and 26 may be turned upon the shaft 10 bringingthe slots32 into ahnement with the slot 16 of the shaft and therebypermitting the free longitudinal movement of the bolt 15 outwardly andinwardly v ofand'within the slot 16. 'It is noted that the lugs 29 ofthe bolt 15 are of greater dimension-s than'the lugs 28 carried by thehead 14. It will be seen that the three mem- ..bers 25 and the endmember 26 may be read.-

ily positioned upon the shaft when the' bolt is removed while the slots32 may then be positioned in alinement with the slot'lfi permitting theinsertion of the bolt 15 within the slot 16 bringing the dowels23'within the sockets 22 and the shackle in its? closed operativeposition. the members '25 and 26 in any direction, the combination willbe broken and the bolt 15 will be locked by the permutation membersagainst bein Withdrawn. Upon again setting the combination, the slots 32of all hf'the permutation members and 26. will be again brou ht intqalinement with each other outward y. of the slot "16 permitting thewithdraws! of the bolt 15 and the free i a passage of the iugs 29 of thebolt 15 through the said slots 32.v It. is obvious that 'any dosirablecharacters 27 may be empl'o ed with any of the same arranged outward yof the slots 32 'nd when the same are arr'anged in .a straig t line andin line wih such an indicia as the points 33 upon the heads '11 and 14,the combination will be 1n its releasing position for permitting thesame movement of the bolt 15.

I familiar therewith,

v .Thecomplete operation of the device will be apparent from thisvdetailed description thereof it being seen ',that a permutation pad-lockis arranged giving great security and which is eas ly operable by aperson What I claim is =-g l 1. A look comprising cooperating shacklemembers provided with heads, a slottedshaft carried by one of saidheads, a bolt carried bythe other head. adapted for reception within theslot of said shaft, lugs By turning.

shaft, lugs on the bolt of tgreater dimensions than the lugs on the shaand arranged to lie in the same transverse plane as the slotted-shaft111 s when the bolt and shaft are in assemble position, a plurality ofringlike permutation members having laterally centrally aperturedannular chambers, said permutation members being mounted on the shaftfor rotation thereon with the lugs of the bolt and the lugs of the shaftpositioned within the permutation members when in locked position, saidpermutation members having radial side slots of greater dimen sions thanthe lugs-of the bolt and adapted to engage the boltlugs outwardly of theshaft slot when the shackle members are in unlocked position.

2. A lock'of the type described, including cooperatin shacklemembershaving interfitting soc et and dowel connection, and

adapted to form a keeper for the reception of the lock-attaching means,said shacklemembers being provided with circular heads, one of saidshackle-members being provided with a slotted shaft having lugs on theop posite sides thereof and the other shacklemember being provided witha bolt received by the slot of said shaft, said bolt having lugs ofgreater-dimensions than the lugs on the shaft and arran ed to lie in thesame transverse plane as t e shaft lugs when the members of the lock areassembled, a plurality of ring-like permutation members having laterallycentrally apertured annular chambers, said permutation membersdimensions than the lugs of said bolt and adapted to engage said boltlugs outwardly of the shaft-slot when the device is in its unlockedposition.

In testimony whereof I afiix my signature.
